■ and the “Necessary Evil: Super-Villains of DC Comics” feature-length documentary from Warner Bros Home Entertainment that focuses on DC Comics’ villains — including the Joker, Lex Luthor, Bane, Black Adam, Black Manta, Catwoman, Darkseid, Deathstroke, Doomsday, General Zod, Sinestro, and the Suicide Squad — that Christopher Lee narrates. Directors Richard Donner, Guillermo del Toro and Zack Snyder, as well as DC’s chief creative officer Geoff Johns are featured in the film, which will also be sold separately for around $19.98.

“I am delighted to be participating in this documentary which really gets to the heart of what villains are,” Lee has said. “Even though I’ve played the hero more times than the bad guy, people remember me for the latter, perhaps because villains are more interesting and more complex. But they’re still people. Tony Hopkins was right when he said, ‘I don’t play villains, I play people.’ Each of these characters has a different personality and their reasons for being or becoming evil are not the same.”

“Batman: Arkham Origins,” developed by WB Games Montreal, is the third installment of Warner Bros. Interactive successful Batman franchise, and serves as a prequel storyline set several years before the events of “Batman: Arkham Asylum” and “Batman: Arkham City.” Game focuses on the rise of Gotham City’s most dangerous criminals, and features a younger untested Batman.
